members, and' in suchinstances, vfor example,l

the blade has been secured inl position in the razor frame by a carn Operated by -a f lever. One of 'the 'features ot my presenty invention isf-to Aso construct an safety razor in which Va pivoted'guard memberis ein@ ployed so. that there will be a double or `'dual gripping action between the-guard andthe razor blade and the frame of the razor, and

also betweenthe handle and itsl attachment to the framefoi' the razor so as to prevent the handle `from twisting and becoming loose in the frame in the usev of the instru'- ment. I am also aware that heretoforev it has been proposed in'satety razor structures to employ a rod or spindle passing through thev handle Y and p adjustable from vthe `end thereof to engage a razorl blade to secure the same in'position inthe trame of the razor, but so far as I am'aware no sat'ety razor structure has been heretoifore `devised in which the double yyield-ing gripping ac- Vtion has beenproposed Oremployed.` In the razor as constructed in accordance wlththis invention, the securing ofthe razor lblade in position bythe adjustable device is operative from the end of the handle whic'hdevice also causes ay gripping action between the 'connection between 'the handle and the'` razor frame so as to prevent the handle from turning in the frame "when the razor is being used. This safety razor Valso includes a cap or 'cover which also acts Vas ali-support or holder for the razor-blade, if necessary, in removingA the same troni-the frame, and this is another novel featurev of thepresent invention. Furthermore, in ther razor made in accordance with this invention, the guard Y memberfmay be vso constructed as to be removable from the-fra1ne and thus; adjustable to position therein so that byadjusting the guard member to any one o-its pivotal positions or vemployingdiiferent guard members 111 and 12 respectively.

bers', the-:relative positionsv of the edges of the razor blade to the comb'section of the guard member may be .varied depending upon the cut which'itfisfdesired to make by 'the'. instrument `,jthat is, Whether itv is" desiredv tOmake'a-'short cut to obtain a close V- shave or along cut tok obtain'a shave which is'not so close'andl `smooth.- These, with other features of my invention, will be hereinafter more particularly described.

endrmeinbers 11, and-'12 and a-base portion 18v in which thereis an opening 14 whichis tapped'y and` adapted. to receive a :screw' threaded shankl providedy for' this purpose" at one end otfa handlef 16. The frame or body of the razor 'also includes vguide members y17 Aand 18 whichare inturned at right angles from the upper-edges of the end mem- The 'razor also includes'a guard member,

thel body portion oftwhich is. indicated 'at f 19 and which at the extremities is provided with ends 20 and 21 formed at'right angles thereto and adaptedtotwithinand extend between the end members 11 and 12 of the body ot' therazor. As illustrated in Figs. .1, 2 and- 3 ofthe drawing, the guard memb'errmay be pivotally connected vto the' end members of the frame at the pivots indicated at 22 and 23. yThis pivoted guard member is provided with a comb structure adjacent the outermost'edge when the guard is in position in the frame, this edge of the pivoted guard being indicated at 24 adjacent which the edge portion of the guardV iscurved as indicated at 25,'the combnstruc-A ture inthis portion ofthe pivoted guard being. provided with series of ,preferably parallel slots 26. lAt the' extremities of the guard-memberithe endportions 20-and 21 thereof have the usual 'stop arms 27 and 28 to Vdetermine the position `of the razor Yblade when(l placed inthe frame,l one. surface of the razor blade at the endslthereof bearing against thesestop arms andthe edgeV of the razor blade atthe extremities thereof contacting with projections 29 and 30 turned up respectively at theextremities ofthe'stop arms to properly position the razor blade relativelyv to the pivotal guard and ythe frame. .f On the inneror under side of the pivotal guard v.member I fix a plate 31. This plate 31`maybe secured `to the guardymemi ber by rivets 320i' otherwise, and approximately centrally there are recesses 33 in the outer edge of the plate 31 so as to provide. Va spring 34 provided in'its inneror under surface with'fa recess 35 for;V the purpose J whichA willbe hereinafter indicated. Also as illustrated, a: plate 36 may besecuredfto :the plate ',3'1 by. rivets37 or otherwise, and this plate 36 is provided with an extension 38, the `material of which. the plate 36 is made being .sufficiently resilient to cause the projection 38 when properly bentor 'curvedy to function asv a-spring for lthe purpose also hereinafterindicated. The upper edge of the frame body ,10, is centrally recessed as indicatedat 39in order kto receive the spring projection 38 when the Apivoted guardmember is in a 'releasedpositiou In constructing the `razor made vin yaccordance with this invention, I also employ :a

cover member 40..4 This cover member in-` cludes a flange 41, the`end42 of Awhich vis centrally extended and outturned to act in conjunction with the .spring extension 38 tion for use in which it extends over4 the to maintain the cover vyieldingly in its posilarger portion of the razor blade when in positionV in the instrument, and also by the connection of the plate '37 to the guard member to exert a yielding pressure upwardly applied at approximately the central por? vtion ofthe guardV so as to cause the rsame to yieldingly press against the razor blade when inplace. `The flange 41 of the cover is also providedwith an aperture 43 of sufficient length? when in the proper position to vre- 'ceive thespring extension38 of the flange of. the cover when the cover is turned out ofits norma'loperativeposition and to the dotted line' position, for example, as shown in Fig.' 1 inwhich the cover acts asa sup-y port for receiving the razor blade, if so `made.

desired, when the razor blade is removed from the instrument. Furthermore, the covermember, as clearly indicated in Fig. 2 of the drawing may be provided with notches or cut away portions 44 in order to clear the guide members 17 and 18 and per-L ro Y mit the free edge of the cover to come into contact with the outer surface of the razor blade when'the instrument is in use. v

The handle member 16, as illustrated, is

provided with bores of different diameters,

one of these bores is indicatedfat45 and is oflarger diameter than the other borewhic'h i Y is indicated at 46 so that' a shoulder 47 is provided interiorlyrin the handle'l, I also employ a rod 48 which is ofk Vsuch a diameter as to pass through and snugly fit in thebore 46. The rod 48, at one end, isr adapted to fit into the recess 35 provided in the spring member 34, and at its opposite end withinl the bore 35 of the handle is provided with a head 49 which preferablyisof such adiame- Y ter as to snugly fit,butto be movable in the bore 45. SurroundingV the rod 48 and extending between the shoulder 47 andthe .ad-V 'jacent siderof the head 49 there is a helical springO. The outer-.endfof 'the handle is fitted with. a button 51 `having-.a screw threaded shank or extension 52 adapted tol fit and be turned to position inthe tapped `Outer-,.endvof the. handle meinbenlt will now be understood vthat the tensionof. the

spring 50 is sulicient tonormallyforce and 'l maintain the head 49 againsttheiendy of the shank 52 and that in using the instrument the button 51 is unscrewed so that (the head removed from fthe .spring 34. With the parts in this position andthe cover turned back to -49 may follow the shank 52 andV in sodoing Y c Y Y cause the opposite endjof the rod 48v to beYV the instrument so that'l with this yielding pressure, as well as that exerted by the cover memberthrough the spring extension38 the izo guard member is forced against the blade when in position by the double yielding grip to which reference has hereinbefore vbeen Furthermore, in so .adjusting-the parts to place it will be understood that the action of the-spring 50 coacting withtherrod 48 and through the tensiony placedfon the l pivotal guard member Vexerts an; increased A friction between the inner end of they handle isc the dotted line position shown in Fig. 11, the 'razor vblade 1s placed on the pivoted cguard and the adjacent portion of the base 13 of the frame of the razor with which it contacts, causing a sufficientwfrictional Contact between these parts to 'prevent the accidental loosening Vof the handle by turning in the frame during the use of the inst-rw` y ment.

Y By reference to Figs. 6, 7 and 8it will be seen that the guard member instead vof being connected positively, that lis lixedly in the frame member yIby the pivotal points, may

removably connected therein by providing pinsy in the router ends of the frame membersV l1 and 12 and providing the ends 2O and 21 of the guardmember with slots` 5,4 adapted to receiveV the pins 53 so that any one of V-a number of different guard inembers may Abe removably connected tol the frame sopas to be lpivotally mounted therein, t-hese v.guard members being so constructed that therelative vdistances from the edge of .the blade to the edge of the guardV is `different sol asV to determine the nature of the cut whichfis made by tlfieinstrumentl in the use thereof. l, f
